Nurse Call Flashcards
To be classified as nurse call system in BC, the system must be…
Hardwired
CSA listed as a complete system
Approved as class 8711 electromedical equipment
LT1 pg.9
The complexity of the system depends on
Facility size and type
Degree of care
Cost
LT1 pg.9
What is the order of complexity systems are described in?
Visual Audio-Visual Computer-based audio-visual Centralized Specialty
LT1 pg.9
What components is a basic call system made of?
Bedside call station Staff or emergency call station Bathroom call station 1+ corridor lights Floor control station Area control unit
LT1 pg.9
What is the purpose of a call station?
To provide patients, hospital personnel, or non-medical people with a way to communicate a need for help for a patient.
LT1 pg.9
What device provides a patient with a way to summon help?
Bedside call station
LT1 pg.10
Does anything happen within the nurse call system if a bedside call station wall assembly has no cord connected to it?
Yes, because the bedside call station is part of an electrically supervised system, no cord in the wall assembly will initiate a call.
LT1 pg.10
What is a “dummy plug”
A device that must be inserted into the outlet jack of the wall assembly of a bedside call station to prevent a call from being initiated.
LT1 pg.10
What is the purpose of a staff call station?
To indicate to other hospital staff the location of a call when security and/or staff safety may be an issue.
LT1 pg.11
What is required to ensure a patient is completely isolated from electrical circuitry in a bathroom call station?
A pull string with an insulating link.
LT1 pg.11
What is the purpose of a duty station?
To alert nurses of calls, when they are away from the call station, using lights and tones.
LT1 pg.12
What is one main difference between staff stations and duty stations?
They are programmed differently from each other
LT1 pg.12
Zone lights indicate…
The general area of a call.
What kind of electronic circuitry do modern nurse call stations use?
CMOS based electronic circuitry.
LT2 PG21
Where are corridor indicator lights?
Outside every patient room.
What are corridor indicator lights for?
A visual signal directing hospital staff to the room a call comes from, it also communicates the type of call by using different coloured lights.
What is a zone indicator?
A visual signal that directs hospital staff to the general area, or zone, that initiated the call.
Where is a floor control station located?
The nursing station.
What is the purpose of the area control unit?
To provide power for each individual nurse call system.
Centralized indication of a room initiating a request.
Floor Control Station
Self Test 1
Pull cord operated by patient in bathroom.
Bathroom Call Station
Self Test 1
Coordinates and controls the system.
Area control unit
Self Test 1
Patient wants help.
Bedside Call Station
Self Test 1
Hallway indication of room initiating request.
One or more corridor indicator light
Self Test 1
Nurse wants help with patient emergency.
Emergency call station
Self Test 1
Hallway indication of zone initiating request.
One or more corridor indicator light.
Self Test 1
Notifies when staff is in a room.
Staff Station
Self Test 1
What effect does a failure in one part of a nurse call system have on the rest of the system?
The remaining system operates normally.
Self Test 1
Where is the logic or controls for any patients room located?
In the components of that room.
Each room acts independently from every other room and sends signas to central control.
Self Test 1
What are the advantages of a wireless nurse call system?
Nursing staff know immediately from anywhere in the hospital which patient initiated a call and can communicate by voice with the patient.
Self Test 1
CMOS is susceptible to damage from static discharge.
True
LT2 Pg21
What happens to the system, or other rooms, when there is a fault in one room?
A fault in one room does not effect any other room.
LT2 Pg21
What may be considered a zone?
A wing, corridor, or specialized area.
LT2 Pg21
If the nurse call system is interconnected with other systems within the facility (entertainment, phone, computer patient monitoring), what stringent guidelines must be ensured?
Must have electrical isolation from other systems
The failure of any other system will not have an adverse effect on the operation of the nurse call system
LT2 Pg21/22
What class of wiring does the CEC designate to nurse call wiring?
Class 1
LT2 Pg24
What does a class 1 designation do for nurse call wiring?
Requires that the cabling must be kept clear of communication cabling, power conductors, lighting conductors. This separation reduces the possibility of interference.
LT2 Pg24
What is a UPS and what does it accomplish?
Uninterruptable Power Source
It ensures that the nurse call system is always connected to power.
LT2 Pg24
ULC-1069 requires that all circuits in patient care areas be limited to what VA?
100VA
LT2 Pg25
ULC-1069 Nurse Call Equipment - maximum voltage and power.
1) Max voltage available to equipment installed in areas accessible to patient
2) Max power available to low voltage equipment installed in areas accessible to patient
3) max voltage to control circuit where wet location contact is likely
1) 30v AC, 42.4v DC
2) 100VA
3) 15v AC, 12.4v DC
LT2 PG25
Rule 16-222(3)
Why is a nurse call system tested by an independent testing contractor after installation?
To ensure the system meets the requirements of the CSA
LT2 PG25
What is the maximum amount of time a nurse call system can be without power?
10s
Self Test 2
What are the bonding requirements for a nurse call system?
Bond must be sized in accordance with table 16, but in no case can be smaller that #12AWG
Self test 2
What are the requirements of the branch circuit supplying a nurse call system?
24-102
A separate circuit of #12 AWG copper or larger, at not more than 150v to ground supplied by an essential electrical system
Self Test 2
What is an essential electrical system?
An electrical system in which the interruption of that system may compromise the care, safety, and health of patients.
Self Test 2
What and/or where are the indications when a patient initiates a call?
Corridor indicator
Zone indicator
Floor control station
